Summer Car Care Guide: Keep Your Vehicle Running Smoothly in the Heat

While winter is tough on cars, summer brings its own challenges: high temperatures, holiday traffic, long journeys, and increased air conditioning use. At Auto MOT Centre in Manor Park, London E12, we help local drivers prepare for summer every year. This guide covers everything you need to keep your car running smoothly through the warm months.

Why Summer Car Care Matters

Summer conditions put different stresses on your vehicle:

Heat – Engine temperatures rise, cooling systems work harder

Holiday traffic – More miles, more wear

Air conditioning – Extra strain on the engine

Higher speeds – Motorway driving in hot weather

Sun exposure – UV damage to interior and exterior

Rain and storms – Summer downpours still occur

A well-prepared car is more reliable for holidays and daily driving.

Essential Summer Car Checks

1. Cooling System

Your engine works harder in summer heat:

Coolant level – Check the expansion tank when the engine is cold

Coolant condition – Should be clean, not rusty

Radiator cap – Check the seal is in good condition

Radiator fins – Clean any debris (leaves, insects) that blocks airflow

Hoses – Check for cracks, bulges, or leaks

We can pressure-test your cooling system at Auto MOT Centre to identify any weaknesses.

2. Air Conditioning

A working AC is essential for summer comfort:

Test the AC – It should blow cold within a few minutes

Check for strange smells – Musty odours indicate mould in the system

Listen for noises – Unusual sounds may indicate compressor issues

Refrigerant – Low refrigerant reduces cooling effectiveness

If your AC is not working properly, we can diagnose and repair it.

3. Tyres for Summer

Summer driving puts different demands on tyres:

Tyre pressure – Check every 2-3 weeks; heat causes pressure to increase

Tread depth – Minimum 1.6mm; higher is safer for wet roads

Tyre condition – Look for cracks, bulges, or uneven wear

Wheel alignment – Misalignment causes uneven wear

Consider premium tyres if you do a lot of motorway driving—they handle heat better.

4. Engine Oil

Heat affects engine oil performance:

Check level – Top up if low

Check condition – Dark oil should be changed

Use correct grade – Follow manufacturer recommendations for summer

5. Battery

Summer heat actually harms batteries more than winter cold:

Test battery – Have it tested, especially if it is 4+ years old

Clean terminals – Remove any corrosion

Check hold-down – Ensure the battery is secure

A weak battery often fails in summer when you are running AC, lights, and other accessories.

6. Wipers and Windscreen

Summer driving still needs good visibility:

Check wiper blades – Replace if they streak

Check washer fluid – Use summer-specific screen wash

Check for chips – Repair any stones chips before they crack

Clean windscreen – Remove insect residue and road film

Summer Driving Tips

Before a Long Journey

Check fluids – Oil, coolant, screen wash

Check tyres – Pressure and condition

Plan rest stops – Stop every 2 hours to rest and check the car

Pack an emergency kit – Water, snacks, phone charger, first aid

Check your route – Avoid known problem areas

On Hot Days

Keep the engine cool – Do not let it idle in traffic

Use the AC wisely – Turn it on before the car gets too hot

Park in shade – Protect the interior from UV damage

Check for overheating – Watch the temperature gauge

Driving in Rain

Summer storms can happen suddenly:

Use headlights – Even in light rain

Reduce speed – Wet roads reduce grip

Keep a safe distance – Allow more stopping time

Use fans instead of recirculation – Prevents windscreen fogging

Holiday Car Preparation

If you are driving to a UK destination or abroad:

Before You Go

Full service – Consider a service before a long trip

MOT check – Ensure your MOT is valid for the whole journey

Breakdown cover – Check you have adequate cover

Documents – Bring your V5C, insurance, driving licence

What to Pack

Emergency kit – Warning triangle, first aid, torch

Recovery equipment – Jump leads, basic tools

Fluids – Water for you and the car

Snacks – In case of delays

Entertainment – Keep children occupied

During the Journey

Take breaks – Every 2-3 hours

Check the car – At each stop, glance at tyres and gauges

Stay hydrated – Dehydration affects concentration

Watch for fatigue – Swap drivers if possible

AC Maintenance Tips

To keep your air conditioning working efficiently:

Use it regularly – Run the AC at least once a week, even in winter

Use recirculation wisely – Use fresh air mode occasionally to prevent mould

Clean the filter – If your car has an accessible cabin filter, clean or replace it

Get it serviced – If cooling is poor, have it checked for leaks or low refrigerant

Protect Your Car’s Interior

Summer sun can damage your car’s interior:

Use a sunshade – Protects the dashboard and seats

Park in shade – When possible

Use leather conditioner – Prevents cracking and fading

Clean regularly – Remove dust and debris that can scratch surfaces

Consider tinting – Window tint reduces heat and UV damage
